logger.h: reduce maximum payload so sum is page size

Browse source 
Reduce maximum log payload so that the sum with the maximum
length header logger_entry_v4 is a page size. This is a
performance measure.

Expect side effects, truncates messages 8 bytes earlier. The
length has a long history (2008) so there may be non-C code
somewhere that has it hard-coded rather than reflecting this
header. CTS tests may need to be adjusted.
